Yo’ Templar here,
Very fun game, the main mechanic lends itself for some good puzzles and progression of the tools is good.
A thing to keep in mind if you’ll continue developing this game:
For games like this that with few colours, mostly black, the eyes of the player usually follow the most interesting thing in the environment, for this kinds of games would be the moving elements (Think the player character, platforms, electricity/flow), so it’s a good idea to work on fluid animations for this entities, right now the player animation and the platforms feels “rigid” like a robot, a good example for this would be Limbo, if you ever played that game you should notice how every animation is fluid, including the way the player interacts with the props in the environment.
